Page 3: General Information
2. General Information 2.1 On-Board Diagnostics (OBD) II The first generation of On-Board Diagnostics (called OBD I) was developed by the California Air Resources Board (ARB) and implemented in 1988 to monitor some of the emission control components on vehicles. As technology evolved and the desire to improve the On-Board Diagnostic system increased, a new generation of On-Board Diagnostic system was developed. -

6. Ready Test This function can be used as a convenient readiness test tool by automotive technicians to determine if the tested vehicle is ready for an emission test. By visual and audible indication, you will learn a vehicle’s monitors readiness. 6.1 General Information Repairs to the emissions-control systems of a 1996 or newer vehicle cause the vehicle‟s computer (ECU) memory to be cleared. - Page 60 The purpose of this function is to indicate which of the vehicle‟s monitors have run and completed their diagnosis and testing, and which ones have not yet run and completed testing and diagnosis of their designated sections of the vehicle‟s emission system. All data shows on one screen, which provides a simple profile of vehicle at a glance, saving diagnosis time and improving technician productivity.
- Page 61 After the erase procedure is performed, status of most monitors will be changed. Leave the scan tool connected to the vehicle, and select Ready Test from Main Screen. Keep on driving the car till the scan tool notifies you safely with color LEDs and audible tone that the drive cycle has been completed and the vehicle is ready, eliminating drive cycle guesswork and confirming readiness status.
-
Page 62: Led And Tone Interpretation
NOTE: This function reads off the real time data of emission-related monitoring systems readiness status. Once the scan tool has finished other operations, for example, clearing trouble codes, the I/M Readiness Monitor Status program resets status of all the monitors to “INC” condition. In order to set these monitors to a Ready status, the vehicle must be driven through a complete drive cycle. - Page 63 “INC” -- Indicates that a particular monitor being checked has not completed its diagnostic testing. “N/A” -- The monitor is not supported on the vehicle. The LED and audio tone indications are interpreted as below: LED Interpretation The green and red LEDs provide an easy way to check if emission-related monitoring systems complete their self-diagnostic testing.
